The NA2P125 is the original full-size, one-inch-per-pole format — not the thin twin body — so it seats correctly on the bus without adapters or modification. It delivers thermal-magnetic Long-Time and Instantaneous (LI) protection with a 10kA short-circuit rating at 120\/240VAC and common trip linking both poles. Where original stock is unavailable, the UBIFPE125N is a recognized modern substitute for this position.\u003c\/p\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eBrand\u003c\/th\u003e\n\u003ctd\u003eFederal Pacific (FPE)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eSeries\u003c\/th\u003e\n\u003ctd\u003eNA — Stab-Lok\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePart Number\u003c\/th\u003e\n\u003ctd\u003eNA2P125\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAmperage\u003c\/th\u003e\n\u003ctd\u003e125A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eVoltage\u003c\/th\u003e\n\u003ctd\u003e120\/240VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePoles\u003c\/th\u003e\n\u003ctd\u003e2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003ePhase\u003c\/th\u003e\n\u003ctd\u003e1\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eAIC Rating\u003c\/th\u003e\n\u003ctd\u003e10kA @ 120\/240VAC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eMounting Style\u003c\/th\u003e\n\u003ctd\u003ePlug-On (Stab-Lok)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTerminal Type\u003c\/th\u003e\n\u003ctd\u003eLugs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eFor Use With\u003c\/th\u003e\n\u003ctd\u003eFederal Pacific Stab-Lok Panelboards and Load Centers\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTrip Technology\u003c\/th\u003e\n\u003ctd\u003eThermal Magnetic (LI — Long-Time, Instantaneous)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eTrip Adjustability\u003c\/th\u003e\n\u003ctd\u003eFixed\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWire Range\u003c\/th\u003e\n\u003ctd\u003e#4 AWG – 2\/0 AWG\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eWidth\u003c\/th\u003e\n\u003ctd\u003eFull Size — 1 inch per pole (2 inches total)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eModern Substitute\u003c\/th\u003e\n\u003ctd\u003eUBIFPE125N\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eStandards\u003c\/th\u003e\n\u003ctd\u003eCSA C22.2 No. 5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eApprovals\u003c\/th\u003e\n\u003ctd\u003eCSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eConstruction Features\u003c\/th\u003e\n\u003ctd\u003eStab-Lok System, Common Trip, Full-Size Body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eOperating Temperature\u003c\/th\u003e\n\u003ctd\u003e40°C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShipping Dimensions\u003c\/th\u003e\n\u003ctd\u003e6 x 6 x 6 in\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eShipping Weight\u003c\/th\u003e\n\u003ctd\u003e3 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth scope=\"row\"\u003eCondition\u003c\/th\u003e\n\u003ctd\u003eUsed — 1 Year Warranty\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003ch3\u003eWhat condition is this NA2P125 in, and is it warrantied?\u003c\/h3\u003e\n\u003cp\u003eIt is a used unit, tested and sold with a 1-year warranty.
